Hanne Ludvigsen serves as a Visitor (Faculty) at Aalto University's Department of Electronics and Nanoengineering. With a distinguished career spanning over three decades in photonics and fiber optics research, she maintains active contributions to the field as evidenced by her 196 research outputs and ongoing professional activities. Her educational background includes a Doctoral degree in Engineering and Technology from Helsinki University of Technology (awarded April 26, 1994), a Licentiate degree in Engineering and Technology from the same institution (awarded December 11, 1990), and a Master's degree in Natural Sciences from Aarhus University (awarded May 18, 1985). Ludvigsen's research focuses on advanced photonics applications, particularly in supercontinuum generation, optical interferometry, and fiber optic sensing technologies. Her work bridges fundamental optical physics with practical engineering applications, with significant contributions to surface plasmon resonance sensors, microstructured optical fibers, and high-resolution measurement techniques. Her fingerprint analysis shows strong activity in Supercontinuum Generation, Optical Interferometry, and High Resolution physics, with additional expertise in operators mathematics, linewidth analysis, data analysis methods, glass fiber technology, and light source development. Her publication record demonstrates consistent research output since 1992, with peak productivity between 2003-2005 (20 publications in 2005). Her most recent work continues to focus on photonic crystal integration, surface-core fiber applications, and advanced interferometric techniques for characterizing microacoustic components. Distinguished honorary OPTICA Fellow (2024) Distinguished honorary OSA Senior member (2021) Docent (Optical metrology) at Helsinki University of Technology (1997-present) Ludvigsen has served as Principal Investigator for Academy of Finland-funded research on surface-plasmon resonance sensors based on microstructures optical fiber (2015-2018). Her academic service includes editorial work as a member of the Optics Letters editorial board (2020-2026), participation in numerous conference committees including the European Conference on Optical Communication and Latin America Optics and Photonics Conference, and evaluation activities for the IEEE Photonics Society Young Investigator Award Committee and H.C. Ørsted Marie Curie Fellowships. Her laboratory work has centered around advanced optical measurement techniques, particularly utilizing supercontinuum light sources for interferometric applications and developing novel fiber optic sensor configurations. Her research group has explored surface-core fibers for plasmonics and sensing applications, as well as techniques for characterizing surface acoustic waves and microacoustic component vibrations.
